Zintl相通过引入氢化物阴离子(填隙式阴离子)或通过H与聚阴离子的共价键合(聚阴离子阴离子)形成阴离子,这产生各种不同的组成和键合情况。氢化物(氘化物)的SrGe,BaSi和BaSn的制备氢化(氘化)的CrB型Zintl相AeTt和其特征在于实验室X射线,同步辐射,中子衍射,NMR光谱,和量子化学计算。SrGeD_(4/3)-x和BaSnD_(4/3)-x是由Tt原子组成的六元稠合的船形环,由Zintl相中的三个Z字形链连接而成。这些新的聚阴离子基序均以共价键合的H原子封端,d(Ge-D)= 1.521(9)π,d(Sn-D)= 1.858(8)π。另外的氢化物阴离子位于Ae 4四面体中,因此,代表了间隙式双晶和聚阴离子双晶的特征。BaSiD_(2-x)保留了Zintl相的Z字形Si链,但在氢化物(氘化物)中,它被H(D)原子封端,从而形成d(Si-D)= 1.641(5)Ω的线性(SiD)链。
Zintl phases form hydrides either by incorporating hydride anions (interstitial hydrides) or by covalent bonding of H to the polyanion (polyanionic hydrides), which yields a variety of different compositions and bonding situations. Hydrides (deuterides) of SrGe, BaSi, and BaSn were prepared by hydrogenation (deuteration) of the CrB-type Zintl phases AeTt and characterized by laboratory X-ray, synchrotron, and neutron diffraction, NMR spectroscopy, and quantum-chemical calculations. SrGeD4/3–xand BaSnD4/3–xshow condensed boatlike six-membered rings of Tt atoms, formed by joining three of the zigzag chains contained in the Zintl phase. These new polyanionic motifs are terminated by covalently bound H atoms withd(Ge–D) = 1.521(9) Å andd(Sn–D) = 1.858(8) Å. Additional hydride anions are located in Ae4tetrahedra; thus, the features of both interstitial hydrides and polyanionic hydrides are represented. BaSiD2–xretains the zigzag Si chain as in the parent Zintl phase, but in the hydride (deuteride), it is terminated by H (D) atoms, thus forming a linear (SiD) chain withd(Si–D) = 1.641(5) Å.
